The Sir John Herschel Collection
The preparation of the print Calendar of the Correspondence of Sir John Herschel (Michael J. Crowe ed., David R. Dyck and James J. Kevin assoc. eds, Cambridge, England: Cambridge Univ. Press, 1998, viii + 828 pp) which was funded by the National Science Foundation, took ten years. It was accomplished by a team of seventeen professors, visiting scholars, graduate students, advanced undergraduates, and staff working at the University of Notre Dame.
The first online version of Calendar was created in 2009 by Dr Marvin Bolt and Steven Lucy, working at the Webster Institute of the Adler Planetarium, and it is that data that has now been reformatted for incorporation into Ɛpsilon.
Further information about Herschel, his correspondence, and the editorial method is available online here: http://historydb.adlerplanetarium.org/herschel/?p=intro
No texts of Herschel’s letters are currently available through Ɛpsilon.
Expresses condolences on death of Mary Maclear.
Has pleasure in informing JH that a parcel of publications of the Academy is being forwarded to him.
Sending some reports of the Meteorological Dept. Would also like to send a wind-glass and a 'watch=aneroid' but has refrained as he knows JH is encumbered with many such things. Encloses a note from Charles Green (Rush's air pilot). Sends a few more notes for his rain collection.
Has sent the packet of letters written to Francis Baily to Greenwich, but kept back one or two including the one on the R.S.L. Secretaryship. Is told that James South is now suffering from deafness. Has sent a paper on errors of observation to Cambridge. Comments on this.
Thanks for RF's daily barometric reports in the Times; comments on RF's investigation of the 'Royal Charter' storm.
Regarding the unsuitableness of the weather for astronomers. Sends an answer to one of JH's equations. Regarding the quarrels of Sir James South. Sends some nursery rhymes that seem appropriate.
Will incorporate his suggestion respecting the introduction of the current Julian date in the Nautical Almanac. The name 'Baucis' has been proposed for No. 59. Has sent U. J. J. Leverrier his own views on nomenclature. Bishop's Observatory may be moved to Twickenham.
Thanks for the receipt of the Radcliffe catalogue of stars, but wishes observations had been equatorial rather than circumpolar.
Sending a copy of his work 'Our satellite,' and would be grateful for any comments.
Is obliged for JH's letter acknowledging the receipt of the Radcliffe Catalogue; regrets the delay and will inquire into the cause. Has purchased R. C. Carrington's transit circle for the Radcliffe and would welcome JH's advice as to its employment.
Regarding electro-magnetic forces. His father's health is good.
Stresses importance for Balloon Committee of obtaining corresponding temperatures and pressures; describes two highly sensitive thermometers that might be built for this purpose.
Suggests an observational program for RM's newly purchased transit circle [see RM's 1861-10-21].
Updates JH on activities of Balloon Committee, and thanks him for suggestion regarding temperature measurement. Mentions improving health of Mrs. Sykes.
